Hardware Description

4.3 Ethernet Interface

The AM273x EVM supports an RGMII Ethernet port to provide the connection to the network. This interface is
intended to operate primarily as a 100Mbps ECU interface and can also be used as an Instrumentation Interface.
The AM273x EVM supports following features:
• Full Duplex 10Mbps/100Mbps wire rate Interface to Ethernet PHY over RGMII, parallel interface
• MDIO Clause 22 and 45 PHY management interface
• IEEE 1588 Synchronous Ethernet support
The Ethernet port is interfaced to the AM273x through the Ethernet PHY DP83867ERGZR, and is used to
stream the captured data over the network to the host PC.
